(JACKSONVILLE, FL) - First place in the AFC South is on the line tonight as the Indianapolis Colts are in Jacksonville to face the Jaguars.

The Colts lead the division at 5-and-0 while the 4-and-1 Jags are just a game behind.

Colts quarterback Peyton Manning enters the game just two touchdown passes behind hall-of-famer Johnny Unitas on the franchise's all-time list. Unitas threw 287 TD passes with the Baltimore Colts from 1956 through 1972 and still holds franchise records for pass attempts and passing yards.

The Colts appear to be healthy for tonight's game. Receiver Marvin Harrison and linebacker Gary Brackett, who missed practices earlier in the week, were back on the practice field Saturday. Harrison bruised his left knee against Denver three weeks ago and sat out the Colts' win over Tampa Bay in week five. Brackett has what is listed as an abdominal injury.

Harrison, Brackett and linebacker Victor Worsely were listed as questionable on Friday's injury report but Head Coach Tony Dungy is confident all will be available.
